Where are the world's best restaurants?

From "Snail Porridge" to a "Spherical Egg of White Asparagus with False Truffle", eating out has become a culinary adventure, with restaurants around the world trying out new, exciting - and sometimes bewildering - dishes.

According to market research group Companies and Markets, the booming global restaurant industry is predicted to expand further, hitting $3.5 trillion in revenue by the end of 2016.

Many of the world's cities claim to have the best restaurants – be it the U.K., home to chefs like Gordon Ramsay and Heston Blumenthal, or America, with its thriving foodie scenes on the east and west coasts.
